Unity Energy Corp. announces that it has engaged Geotech Ltd. to conduct a heliborne VTEM geophysical survey over its Close Lake, Lampin Lake and Hoppy Lake Projects in the northeastern Athabasca Basin. VTEM is highly effective at locating discrete conductive anomalies, magnetic features extending to the basement and mapping lateral and vertical variations in resistivity and is a leading edge solution for uranium exploration in the basin. VTEM is an evolving technology and this latest generation boasts a higher sensitivity, achieved by noise reduction and optimization of transmitter current waveform along with dipole moment increases. The low noise level significantly extends conductance aperture and conductance discrimination. The survey will comprise of ~1300 line kilometers with 100m spacing and is expected to be completed within two weeks.
The Company was very impressed at the capability and resolution of the VTEM survey, which in 2010 helped to define three high priority targets at Unity’s Waterbury Lake Project, which is just ~10km south of the Midwest Mine and Hathor’s Roughrider Project. The Company is also in the process of finalizing arrangements for a ground resistivity survey of targets at Waterbury, which should commence in the near term.
Close Lake Project, which is comprised of a singe mineral disposition covering an area of ~596 hectares, is ~10.6km northwest of the Cigar Lake mine. The Tucker NE conductivity trend, which lies immediately north of the CL Property, was delineated by a 1991 Comega (now Areva) ground EM survey and a 2004 MEGATEM Airborne EM & Magnetic Survey. The anomaly was interpreted as a series of 3 or more northeast parallel basement conductive anomalies, the most southerly of which (C-12A) lies ~170m from the northernmost boundary of Unity’s CL property.
The Lampin Lake Project consists of a single 500 hectare disposition located on the eastern margin of the Athabascabasin. The Property is 3.7km southeast of Unity’s Waterbury Lake Property and is bordered by claims held by Dennison to the east (Hidden Bay Project) and Cameco Corporation on all other side.
From 2004-2006, Cameco tested the northeast trending Q12 EM conductor series with ground geophysics and diamond drilling. EM and gravity surveys allowed for the interpretation of the Q12 fault, as well as numerous cross faults that extend onto the Lampin Lake Property. In addition, a northeast resistivity high, extending for ~750m along the southeastern edge of the Lampin Lake Property was defined by EM inversions.
In September 2002, UEX Corporation and Cameco Corporation commissioned a fixed-wing triaxial gradiometer aeromagnetic survey to cover the entire Hidden Bay and Rabbit Lake properties. Goldak Airborne Surveys of Saskatoon, Saskatchewan was contracted to carry out the survey and a total of 6,816 line kilometres of data was collected along 200 metre spaced flight lines. The data collected from this survey was combined with a project-scale EM conductor map to facilitate a regional geological and structural interpretation. Emphasis was placed on identifying the principal geological units, the most prominent structural features, and the areas most prospective for finding uranium mineralization.
The Hoppy Lake Property covers an area of 1924 hectares and is ~10km southwest of the Cigar Lake Mine.
In 2007, Condor Consulting completed an interpretation report for Dejour Enterprises/Titan Uranium and identified a number of Target Zones deemed worthy of follow-up. The report describes the processing and analysis of several VTEM airborne electromagnetic and magnetic surveys carried out for Dejour by Geotech from September-October 2006. The object of the survey was to explore for unconformity style uranium mineralization of both the Simple (Low Rare Earth Elements, (REE) basement-hosted) and the Complex (High Rare Earth Elements, (REE) sandstone-hosted) types.
